When might it be necessary or advisable to write a shell script instead of a shell function? Give as many reasons as you can think of.
What will be an ideal response?
Because the shell executes a shell function in the same environment as the
shell, it can change the values of variables and create new ones. If creating
new variables and modifying existing ones are not desirable, run a shell
script instead.
Having too many active functions can cause a shell to take a long time to
load, such as when you run a script. If you need to call a lot of routines from
a shell, you might want to make some of them scripts rather than functions.
